If you haven’t been raiding recently, you should definitely go out and complete a raid. In this recent maintenance break, Supercell changed the trophy range that you could gain trophies in. Before the most you could gain was +34 and the least was +13. Now, I have found as high as +43 but also as low as +3. Note: these were not revenge raids, just normal, everyday multiplayer raids.
As you can see in the top left it is 43 and 3 trophies available. This also clearly isn’t a revenge raid since there is a next button in the bottom right. Hopefully, Supercell just made a simple error and this will be fixed and returned to the normal ranges. Have a Happy Holiday clashers!
